You're doing just fine. First, if they are groing than you don't have nute lock. Don't worry about seedlings starting out real green. That is normal. You can probably start them on 1/4 strength nutes now.

Don't worry too much about an EC meter. Everyone uses them wrong anyway. Instead, get yourself a digital light meter. I bought one off of Ebay for 30 bucks. Set your seedling for about 500 - 1000 LUX.

Get that going and we'll talk again.
